“Drop Science” is a track by musician Matthew Dear that was built from thousands of sound recordings of jet engines, compressors, diagnostic equipment, and other machines. Dear worked with General Electric acoustics engineer Andrew Gorton to record the sounds of some of the world’s largest machines.

Every machine has its own acoustic signature – a precise frequency that indicates whether that machine is operating at peak performance. GE engineers monitor and record these sounds to perform real-time diagnostics on airplane engines, locomotives, power turbines, and medical equipment.
